Appleinsider posted a small update today reporting that second generation PowerMac G5s would make an appearance by March 2004. The new machines are reported to have advanced features including 533 DDR II RAM support and up to 1.5GHz bus as well as the incorporation of 90nm G5s and "Power Tune" technology.

As previously reported, IBM will be presenting 90nm PowerPC 970 technology at the ISSCC in Feb 2004. First reference to "PowerTune" was seen in the advance program (PDF) where it is briefly described under "PowerTune: Advanced Frequency and Power Scaling on 64b PowerPC Microprocessor" (Page 59)


PowerTune is a power-management technique for a multi-gigahertz superscalar 64b PowerPC processor in a 90nm technology. This paper discusses the challenges and implementation of a dynamically controlled clock frequency with noise suppression as well as a synchronization circuit for a multi-processor system.

It's not completely clear how these new machines would fit with Appleinsider's previous claim that PowerMacs would see revisions in January 2004.

As Steve said - very promising roadmap!
This PowerTune feature sounds like one of Apple´s request to be able to cram the G5 in a PowerBook...

1.5Ghz Bus

1.5Ghz Bus... Would it be safe to say these are going to be 3Ghz Chips then?

Actually, the article just says the system controller will suppoprt up to 1.5GHz. Which would seem to put the post-3.0GHz machines will need a revamped controller ...

If the NEXT revision brings the G5 to 3 GHz in March, IBM would be faster designing than they can produce the CPUs ;)
And Steve would have toned down his bragging "within 12 months" for nothing.

This is VERY promising, and VERY realistic.

I am so overjoyed at the thought that Intel is slowing down, and Apple is speeding up.

The G5 truly marks a turning point in the future of Apple Hardware. People will be speaking of this for years to come.

Wow, 1.5 Ghz bus. and I think 2:1 is the largest bus multiplier. i don't think there is a 1.5:1 multiplier. I know there are 3:1, 4:1 and so one. But 1.5 would definetly imply 3 Ghz.

Hmmmmm......

Wouldn't it be neat if all of a sudden Apple had faster clocked chipsets than Intel. My my that would be a nice turning of tables.
:) :D

My Dual 2

Yeah, I got a dual 2, and even though I always want the biggest and newest - Man, my dual 2 is SWEET, and I am very content with it and expect to be content with it for years to come...

... by no means do I need the newest now that I have my Dual 2. Great machine.

for those that bought 2x2GHz machines, don't worry, I will buy them off you. I'm hoping to get 1100 of them :p

the current machines are arguably faster then the current production pcs... Hopefully by march there will be no doubt!!

Hopefully by march I will be rich enough again :)

I have a Dual 2GHz, but I'm not upgrading for a few years. I'm just happy that apple is getting better and better, no matter how 'slow' my G5 becomes compared to their top of the line machine. GREAT NEWS!!!!!! Bring em' on!
